Why Offshore Oil & Gas Buyers Choose TJJ for Castings
Procuring oil and gas castings from overseas suppliers often comes with three major pain points:
- Inconsistent quality – Dimensional deviations or hidden porosity that cause field failures.
- Long, unpredictable lead times – production delays that halt your projects.
- Poor communication & compliance gaps – lack of proper documentation (MTRs, NDE reports).
Our foundry addresses these head-on: we operate ISO 9001:2015 certified processes, employ experienced metallurgists, and maintain a dedicated export team fluent in ASTM, API 6A, and NACE MR0175 requirements. With 20 years of continuous operation and customers across the USA, South America, Europe, and Africa, we deliver reliable castings that pass third-party inspections.
